Don't go into flying for a career or the money. It is too uncertain, there are too many out there earning very little considering the up-front costs. the lifestyle is too difficult, puts too much strain on your outside relationships. Learn to program instead and go into management in a specialised tech field in which you will be a £500-a-day consultant in 3 or 4 years.
Go into aviation because you love flying, because you really can't stomach going into an office 9 'til 5 every weekday until you draw a pension. Go into flying because you love uncertainty, the chance that takes you to a new city or the flight deck of a new jet. Go into flying because you want to know that in a years time you might be living somewhere new, doing a totally different type of job. Go into flying because you want to be wandering round a new city in a country you hadn't even visited until last week, having arrived in an aircraft type you hadn't flown until this year, where you speak none of the language beyond asking for a beer, looking for a restaurant and some of that fine local brew; that was me last night.
So yes, take a few lessons before you decide. If you love it then start to take it further. Do all the courses in your own time, by your own choice, where you want to do them. Fly as far as you can, as widely in as varied conditions, places and machines as you can. Then when you finally can get paid to fly look into every type of aviation. Try a few of them if you get the opportunity.
You will live in penury for a few years, having the greatest fun with some of the best people around. You will kick the arse out of life, burning the candle at both ends. You can even stay there, in the dirty, fun end of the business for life if you can take the poor pay and the conditions. Some do.
So no, never, ever, ever do an integrated course; they lead only to large airlines who want automata for the right seat. If you want to operate a computer with a nice view from the office, go into the oil business and move to Calgary.
That is my view of the aviation business. There are many other views. Some love the airlines, but I know more who complain about them and are there for the pay check. Some loathe the dirty and uncertain reality of general aviation, but others would not even look elsewhere.
